Study Notes
Goals and Objectives
- Define criminalistics, highlighting its role in forensic science.
- Understand the significance of physical evidence in crime investigation.
- Recognize the importance of forensic science in law enforcement.
Criminalistics or Forensic Science
- Involves scientific techniques applied to crime-solving.
- Provides foundational knowledge of physical evidence, linking crimes, victims, and perpetrators.
- Physical evidence examples include photography, fingerprints, ballistics, hair, fibers, drugs, and document examination.
- Aims to establish innocence or guilt using scientific disciplines under legal rules.
Importance of Forensic Science
- Combines natural science principles with legal frameworks.
- Forensic professionals assist law enforcement in solving crimes.
Forensic Chemistry
- Focuses on applying chemical principles to legal issues.
- Important in courts for analyzing evidence and solving legal problems.
History of Forensic Chemistry and Toxicology
- Explores methods for poison identification, with roots in ancient civilizations like Egyptians and Greeks.
- 1813: Mathieu Orfila recognized as the father of modern toxicology.
- Early contributions included developing tests for blood in forensic contexts and using microscopes for analyzing stains.
- Significant figures include:
- Democritus, early chemist studying poisons.
- James Marsh, first to apply toxicology in jury trials (1836).
- Jean Servais Stas, first to identify vegetable poisons in body tissue (1851).
- Edmund Locard, established the first police crime laboratory (1910).
- Lucas and others who advanced forensic techniques like gas chromatography.
Ancient Issues in Forensic Chemistry and Toxicology
- Use of poisons for murders and executions dates back to ancient times.
- Arsenic was notably used as a poison, especially in Roman times.
- Legal systems historically relied on circumstantial evidence pre-systematic investigations.
- The Blandy trial and the Marsh test pioneered scientific methods to detect poisons.
Importance of Forensic Chemistry and Toxicology
- Essential in solving death-related mysteries, determining causes as natural or criminal.
- Allows positive identification of suspects through specimen examination.
- Forensic chemistry aims to trace evidence to individuals or objects.
Crime Laboratory
- A facility for conducting physical and chemical examinations.
- Edmond Locard is considered the father of the crime laboratory.
- Walker McCrone regarded as the father of microscopic forensics.
Units in the Crime Laboratory
- Physical Science Unit: analyzes drugs, glass, paint, explosives, and soil.
- Biology Unit: identifies blood and other body fluids, compares hairs and fibers.
- Firearms Unit: examines firearms and ammunition residues.
- Document Examination Unit: analyzes questioned documents for authenticity.
- Photography Unit: prepares photographic evidence using advanced techniques.
- Toxicology Unit: analyzes body fluids for drugs and poisons.
- Latent Fingerprint Unit: processes invisible fingerprints.
- Polygraph Unit: conducts criminal investigations using lie detection techniques.
Golden Rules in the Practice of Forensic Chemistry
- Take time for thorough examination; quality work is prioritized over urgency.
- Conduct meticulous and comprehensive analysis.
- Maintain clear records of all actions and findings.
- Consult with experts when faced with unfamiliar issues.
- Exercise disciplined imagination; avoid overcomplicated theories for clear explanations.
